[0024] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a down - drain floor drain with integrated drainage and secondary drainage of the present utility model with reference to the attached drawings.
[0025] As Figure 1As shown in the figure, a down-drain floor drain with integrated anti-drainage and secondary drainage of the present utility model includes a pipe fitting body 1, a waterproof cloth 2, a water seal 3 and an adjustable seat 4. A radially extending groove 11 and a first edge 12 are designed at the port of the pipe fitting body 1. The inner diameter of the groove 11 is larger than the inner diameter of the pipe fitting body 1, so that the pipe fitting body 1 has a secondary drainage function. The accumulated water in the mortar layer or the sunken box can be drained into the pipe fitting body 1 through the groove 11, and the accumulated water on the waterproof layer and under the ceramic tile can be drained away, preventing the accumulated water in the backfill layer from returning and becoming alkaline. The first edge 12 extends horizontally outward from the opening of the groove 11. The first edge 12 has a limiting effect, clamping the pipe fitting body 1 in the opening made on the floor slab and restricting the up and down displacement. The lower part of the pipe fitting body 1 is an arc structure 13, which is more conducive to the flow of water, making the water flow smoother and the drainage efficiency higher. The pipe fitting body 1 is made of PE material, and the bottom connection port 14 can be connected with a PE drainage pipe by hot melting, which is convenient for construction. The outer periphery of the pipe fitting body 1 also has a transverse reinforcing rib 15, which can make the product have a stronger biting force with the cement and will not move up and down. Preferably, the pipe fitting body 1 is integrally formed.
[0026] The waterproof cloth 2 is arranged at the port of the pipe fitting body 1, with the mouth part hollowed out, and the mouth edge is integrally injection-molded with the pipe fitting body 1. The waterproof cloth 2 is made of a flexible material, which can withstand the axial and radial shrinkage of the pipe fitting body 1, and can avoid the generation of gaps between the PE pipe due to thermal expansion and contraction and the backfilled cement and the waterproof layer, resulting in leakage. At the same time, when the waterproof cloth is installed, it can fit the ground, making the floor drain closely combined with the ground to form an integrated structure. This design not only improves the waterproof performance of the floor drain, but also enhances the stability and durability of the floor drain, and is convenient for construction.
[0027] The water seal 3 is arranged in the pipe fitting body 1 and is a standard water seal with a 9-centimeter large buckle, which increases the water flow area and reduces the water flow resistance, thereby improving the drainage efficiency. The end face of the water seal 3 has a second edge 31, and the design of the second edge 31 can effectively prevent sundries from entering the drainage pipe and avoid blockage. The water seal 3 is detachable, which is convenient for cleaning. There is a handle 32 above the water seal 3, which is convenient for taking.
[0028] The adjustable seat 4 is arranged above the pipe fitting body 1 and can be arbitrarily cut according to the height of the mortar backfill. The upper cover covers the adjustable seat 4 and is flush with the decorative layer.
[0029] As Figure 2 Figure 3 As shown in the figure, the implementation process steps are as follows: Determine the installation position of the floor drain, then make a hole and roughen it on the floor slab. Then, place the down-drain floor drain with the waterproof cloth 2 integrally injection-molded with the pipe fitting body 1 at the installation position, making it level with the rough ground, ensuring that the floor drain is the lowest point in the slope. Finally, backfill the hole and unfold the waterproof cloth 2, and use cement to bond the waterproof cloth 2 and the rough ground neatly and smoothly.
